(a) DW velocity versus current density in the presence of a constant in-plane magnetic field in + x and −x-directions for 1-nm-thick Pt spacer; plot symmetry across x-axis reveals low DMI strength. DW velocity for Pt spacer with thicknesses 0.5 nm and 1 nm when a magnetic field was applied along (b) −x-direction, and (c) + x-direction. Comparison indicates increasing Pt spacer thickness reduces velocity.
